Hello, I synchronize currently the port of the FreeBSD timecounters to RTEMS and came across a change in 2019 which I do not understand. Some time ago the timehands were reduced from 10 to two: https://reviews.freebsd.org/D7302 In 2019 this changed again to be up to 16: https://reviews.freebsd.org/D21563 The corresponding sysctl is not documented: https://www.freebsd.org/cgi/man.cgi?query=timecounters&sektion=4 Does someone know why this sysctl to select the count of timehands was added? Is this a performance optimization for some systems?
